The gnome-canvas docs have 2 functions that should do what you want:

int         gnome_canvas_item_grab          (GnomeCanvasItem *item,
                                               unsigned int event_mask,
                                               GdkCursor *cursor,
                                               guint32 etime);
void        gnome_canvas_item_ungrab        (GnomeCanvasItem *item,
                                               guint32 etime);

AFAIK GtkWidgets and CanvasItems don't share any properties, so
GtkWidget-functions don't work on CanvasItems. CanvasItems implement
their own functions.
